I don't know that there is anything that YOU (the HSV neg partner? - have you been tested? ever had symptoms?) can do to help your partner feel less stigamitized (other than NOT stimatizing them). HSV continues to garner a lot more attention than it is probably worth given that the vast majority of infected persons are oblivious and happily spreading the "joy" around unwittingly. So the few, responsible, people who know their status are burdened with the responsibility of educating all of their potential partners for the rest of the masses.
A majority of people (more than 50%) test positive for HSV 1 or 2 by the time they are 40. Knowing which type that you have been been exposed to doesn't necessarily tell you what body parts may be involved (HSV-1 prefers oro-labial, HSV-2 prefers ano-genital, but 20% of cases are in the "wrong" location). Transmission can be decreased by regular prophylactic dosing of antivirals and avoiding contact when pro-dromal symptoms are present. Education is the only answer that I have. She may want to ask prospective partners to get serological testing to find out their status (so they don't end up "blaming" her for an infection they already had). NOTE: HSV is NOT routinely screened for on STI panels - we generally only test if someone has an outbreak and we want to confirm the diagnosis.
